/etc/sysconfig/keyboard is programmed with keyboard information from the manufacturing data. We preferably specify XKB keyboards with the layout(variant) syntax because it's more intuitive when you have two or multiple layouts. The separate layout and variant syntax is still supported.

/usr/share/olpc-utils/xorg.conf.d

This directory contains X configuration files for the various XO laptop models, and sisusbvga output.

olpc-configure maintains hardlinks to these files in /etc/xorg.conf.d, dynamically configured on each boot.

It is our hope that these configurations shrink with time to the point where they can just exist as one static file.
